Abstract:
Objective To investigate the expression of long non-coding RNA(lncRNA)small nucleolar RNA host gene(SNHG)25 and microRNA(miR)-497-5p in glioma tissues and their relationship with clinical features and prognosis.Methods A total of 157 glioma patients admitted to the hospital from January 2019 to January 2020 were selected as the glioma group,and 100 patients who underwent surgical treatment due to craniocerebral injury in the same hospital during the same period were selected as the control group.The ex-pression levels of lncRNA SNHG25 and miR-497-5p were detected in glioma tissues and normal brain tissues resected during operation.The patients were followed up for 3 years.The correlation between the expression levels of lncRNA SNHG25 and miR-497-5p was analyzed,and the relationship between the expression level of lncRNA SNHG25 and miR-497-5p and the clinical characteristics and prognosis of patients were analyzed.Re-sults Compared with the control group,the expression level of lncRNA SNHG25 in the glioma group was in-creased(P＜0.05),and the expression level of miR-497-5p was decreased(P＜0.05).Compared with the maximum diameter of tumors＜4 cm,World Health Organization(WHO)central nervous system tumor grade Ⅰ-Ⅱ,the expression level of lncRNA SNHG25 was increased and the expression level of miR-497-5p was decreased in glioma tissues with the maximum diameter of tumors ≥4 cm and WHO central nervous sys-tem tumor grade Ⅲ-Ⅳ(P＜0.05).The expression level of lncRNA SNHG25 in glioma patients was nega-tively correlated with miR-497-5p(r=-0.370,P＜0.05).The cumulative survival rate of lncRNA SNHG25 high expression group was lower than that of lncRNA SNHG25 low expression group(P＜0.05),and the cu-mulative survival rate of miR-497-5p low expression group was lower than that of miR-497-5p high expression group(P＜0.05).Grade Ⅲ-Ⅳ of WHO central nervous system tumor grade and high expression of lncRNA SNHG25 were risk factors for poor prognosis of glioma patients(P＜0.05),while high expression of miR-497-5p was a protective factor(P＜0.05).Conclusion The expression of lncRNA SNHG25 is increased and the expression of miR-497-5p is decreased in glioma tissues,which is related to the maximum diameter of tumor and high WHO central nervous system tumor grade,and can lead to poor prognosis of glioma patients.
